There's a significant debate going on in the hackerspace/maker community over acceptance of funding from DARPA, the research organization of the US Department of Defense to underwrite the creation of high school makerspaces.
The 'Yes' side of the argument is personified by Dale Dougherty, the founder of MAKE Magazine and Maker Faire, while Mitch Altman, a pioneer in the hacker/maker movement, is vehemently opposed to the point that he is actively boycotting Maker Faires and related activities.
Both sides of the debate are presented in detail by both Dougherty and Altman in the "Makerspaces & the Military" segment on this week's episode of Spark.
For those not already familiar with the excellent programming by Spark, it's a regular 'radio' broadcast (also available via podcast) produced by the CBC. Spark's charter is to create "An ongoing conversation about technology and culture."
